Indications for Use
The Vapotherm Aerosol Adapter AAA-2 is intended to facilitate the connection between Vapotherm High Velocity Therapy HVT 2.0 and the Aerogen Solo Nebulizer.
Device Story
The Vapotherm Aerosol Adapter AAA-2 is a passive accessory designed to connect the Vapotherm High Velocity Therapy (HVT) 2.0 system to the Aerogen Solo Nebulizer. It allows for the delivery of aerosolized medication through the HVT 2.0 breathing circuit. The device is used in hospital and sub-acute settings by clinicians. It functions as a mechanical interface, enabling the integration of the nebulizer into the high-velocity therapy flow path without interfering with the delivery of supplemental oxygen or the aerosolization performance of the Aerogen system. By facilitating this connection, the device allows patients receiving high-velocity respiratory support to simultaneously receive nebulized medications, potentially improving clinical efficiency and patient comfort.
Clinical Evidence
No clinical data. Bench testing only. Testing included aerosolized solution output (laser verification), flow rate verification (8-45 L/min), occlusion alarm testing, rain-out volume assessment, connection integrity (ISO 5356-1), and continuous use durability. Aerosolization performance was validated using a Next Generation Cascade Impactor (NGI) to confirm particle size distribution and respirable dose consistency compared to the predicate. Human factors/usability testing was conducted to identify potential use errors.
Technological Characteristics
Passive mechanical adapter; polymer construction; non-sterile; single-patient use (up to 30 days). Interfaces with 22mm ports per ISO 5356-1. Biocompatibility per ISO 10993-1 and ISO 18562-1. No energy source or software.
Indications for Use
Indicated for spontaneously breathing adult and pediatric patients (5 kg and up, 29 days or older) requiring aerosolized medication delivery via the Aerogen Solo Nebulizer in conjunction with Vapotherm HVT 2.0 therapy in hospital or sub-acute settings.
Regulatory Classification

### Bench / Performance Testing -
Testing was performed to assure that the proposed design does not raise new questions of safety and effectiveness based on the proposed device intended use. Testing included:
Aerosolized solution output testing was performed utilizing a 500mW green laser to confirm delivery, with a nasal cannula patient and trach adapter interface.
Achievable flow rate consisted of testing the AAA-2 with HVT 2.0 while varying flow rates set to 8, 20, and 45 L/min, with varying cannula sizes which included Infant, Pediatric Small, and Adult XL cannulas, to confirm the set flows were achieved.
Occlusion testing with associated alarm included running the AAA-2 with HVT 2.0 at varying flow rates of 3 and 8 L/min for the infant cannula, 3 and 20 L/min for the Pediatric Small, and 3 and 45 L/min for the Adult XL.
The testing described as 'Volume of liquid exiting the adapter outlet' is to demonstrate that excessive rain-out does not occur. The system passed as the maximum of 5 ml of rainout was not exceeded with the AAA-2 placed in a worst-case orientation.
The physical connections testing included challenging all connection points under varying flow rates and worst-case simulated conditions. The 22mm female port that accommodates the connection to the Aerogen Solo Nebulizer was also demonstrated to be compliant to ISO 5356-1.
Continuous use testing was performed while running the HVT 2.0 at varying flow rates and temperatures and there were no signs of component or material degradation.
Aerosolization performance comparison testing for commonly nebulized solutions was completed to demonstrate similar performance for both the AAA-2 Aerosol Adapter and the Aeroneb Solo Adapter when used with an Aeroneb Solo Nebulizer System. To determine particle size distributions and respirable dose of the nebulized solution, nebulized solution respules were collected using the Next Generation Cascade Impactor (NGI) and demonstrated that the use of HVT 2.0 with AAA-2 did not interfere with the expected performance of the Aeroneb Solo device.
Usability/Human Factors testing was performed with results analyzed to identify potential use errors, close calls, and difficulties associated with the critical tasks. The results of this testing supports a substantial equivalence determination.
#### Substantial Equivalence Conclusion
The performance testing demonstrates that the subject device is substantially equivalent to the predicate device.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
